Flat tappet or Roller?

Building a stroked 383, something to cruise and street beat a little with. Keeping it under 5500 rpms. Is it worth the extra grand to go roller step up on the street? I have not wiped a cam yet on flat tappets? I would rather wipe a cam then have needle bearings from a bad roller lifter sent through my motor. FYI, my flat tappet lifters in the existing engine are about 5 years old and plan on reusing them as they do not leak down.
Thoughts? TIA
